弹性搜索，是否可以在搜索结果集中获取特定文档的索引？ [英] Elastic Search, is it possible to get the index of a specific document in a search result set?

问题描述

我知道我想在我的结果集中显示的特定文档的ID，但是我不知道该结果的哪个页面。可以通过弹性搜索来告诉它返回特定文档的页面吗？

I know the id of a specific document I want to show in my result set, but I don't know which page of the results it will be on. Is it possible with elastic search to tell it to return the page that a specific document is on?

我的猜测是这是不可能的。我目前的方法是在加载文档ID后运行查询，并为查询返回一个非常大的（全部）结果集。我找到该列表中的id，然后我再次运行查询，加载我想要显示在页面上的所有数据。我不想运行查询两次，如果我可以避免它。

My guess is this is not possible. My current approach is to run the query once loading just the documents ids and return a very large (all) result set for the query. I find the id in this list, then I run the query again loading all of the data I want to show on the page. I'd prefer not to run the query twice if I can avoid it.

推荐答案

我正在使用JAVA API，索引，类型，ID和来源如下。

I am using JAVA API and I am getting the index, type, id and source as follows.

SearchResponse response = client.prepareSearch().execute().actionGet();
SearchHit[] documents = response.getHits().getHits();
for(SearchHit document : documents)
{
    System.out.println("document index :: " + document.getIndex());
    System.out.println("document type :: " + document.getType());
    System.out.println("document id :: " + document.getId());
    System.out.println("document source JSON :: " + document.getSourceAsString());      
}
